OBJECTIVES: Crimean-Congo Hemorrhagic Fever (CCHF) is a fatal, tick-borne disease. The classic clinical presentation of CCHF is characterized by sudden onset of high fever, chills, and severe headache. There are no previous reports on the characteristics of headaches caused by CCHF. Therefore, we investigated the relationship between CCHF-induced headache and the clinical course of the disease. METHODS: We included 60 patients with headache diagnosed with CCHF; they were divided into two groups: group 1 included patients with hospital stay <7 days and group 2 included patients with hospital stay >7 days...

INTRODUCTION/PURPOSE: Mechanical thrombectomy (MT) for acute ischemic stroke (IS) can be performed also in patients on anticoagulation therapy (AT); however, sufficient and reliable data about safety and efficacy of MT are still missing. Thus, we aimed to compare these parameters between patients treated on AT and without AT. MATERIALS AND METHODS: All consecutive IS patients treated with MT using stent retrievers were included in the retrospective analysis. Neurological deficit was scored using National Institutes of Health Stroke Scale (NIHSS) and 90-day clinical outcome using modified Rankin scale with a score 0-2 for good outcome...

PURPOSE: Imaging findings of pilocytic astrocytoma (PA) vary widely, sometimes resembling those of high-grade glioma (HGG). This study aimed to identify the imaging parameters that can be used to differentiate PA from HGG. METHODS: Altogether, 60 patients with PAs and 138 patients with HGGs were included in the study. Tumor properties and the presence of hydrocephalus, peritumoral edema, and dissemination were evaluated. We also measured the maximum relative cerebral blood flow (rCBF max ) and volume (rCBV max ) and determined the minimum apparent diffusion coefficient (ADC min ) in the tumor's solid components...

Fasudil is a clinically approved Rho-associated protein kinase (ROCK) inhibitor that has been used widely to treat cerebral consequences of subarachnoid hemorrhage. It is known to have a positive effect on animal models of neurological disorders including Parkinson's disease and stroke. However, its cellular effect on progenitor populations and differentiation is not clearly understood. While recent studies suggest that fasudil promotes the mobilization of neural stem cells (NSCs) from the subventricular zone in vivo and promotes the differentiation of the C17...

Cerebral Amyloid Angiopathy (CAA) is one of the significant causes of lobar intracerebral hemorrhage (ICH) mainly among elderly people. Sporadic cases of CAA have been linked to genetic polymorphisms with an increased risk of disease, an earlier presentation, and an accelerated pathology [1]. Here, we present a patient with no significant risk factors who had a recurrent intracerebral hemorrhage secondary to CAA probably induced by exercise.

Despite successful management of ruptured intracranial aneurysm following subarachnoid hemorrhage (SAH), delayed cerebral ischemia (DCI) remains the main cause of high mortality and morbidity in patients who survive the initial bleeding. Astrocytes play a key role in neurovascular coupling. Therefore, changes in the neurovascular unit including astrocytes following SAH may contribute to the development of DCI and long-term complications. In this study, we characterized morphological changes in hippocampal astrocytes following experimental SAH, with special emphasis on glia-vascular cross-talk and hippocampal volume changes...

Internal carotid arterial system is the main source of blood supply in brain. In forensic identification practice, blunt injures of internal carotid arterial system usually cause complications such as thrombus, aneurysm and arteriovenous fistula, etc. The deaths following delayed cerebral infarction or intracranial haemorrhage are not rare. At present, literature of deaths caused by blunt injuries of internal carotid arterial system mainly consist of case reports in China. This paper reviews related literature and case reports at home and abroad, and summarizes forensic medical features and identification method of the deaths caused by such injuries...

BACKGROUND AND PURPOSE: Perturbations in cerebral microcirculation (eg, microvasospasms) and reduced neurovascular communication determine outcome after subarachnoid hemorrhage (SAH). ET-1 (endothelin-1) and its receptors have been implicated in the pathophysiology of large artery spasms after SAH; however, their role in the development of microvascular dysfunction is currently unknown. Here, we investigated whether inhibiting ET A (endothelin A) receptors can reduce microvasospasms after experimentally induced SAH...

The purpose of the present study was to investigate the expression of matrix metalloproteinase-9 (MMP-9) and interleukin-6 (IL-6) in patients with subarachnoid hemorrhage (SAH) and the clinical significance thereof. Forty-three patients with SAH and 23 healthy individuals were enrolled in this study. Patients were divided into the cerebral vasospasm (CVS) and non-cerebral vasospasm (non-CVS) groups, or the good and poor prognosis groups. Serum levels of MMP-9 and IL-6 were detected by ELISA. Expression levels of MMP-9 and IL-6 mRNAs were detected by RT-qPCR...

Methods Patients with cerebral artery dissections were reviewed in a hospital setting from 2008 to 2015. Clinical presentations, lesion locations, treatment modalities, functional outcomes, and mortality were reviewed. Parent artery occlusion was the first choice for surgery or endovascular treatment of a hemorrhagic dissecting cerebral artery. Endovascular or surgical reconstructive treatment was indicated in patients whose parent artery could not be occluded. Favorable functional outcomes were determined using modified Rankin Scale (mRS) scores of 0-2...
